I'am Firas Esbai, a lead data engineer with several years of experience.

My main interest is building intelligent data intensive systems. I focus on design and solving architecture challenges to help businesses thrive with better data-driven decisions, while building high-performing teams that drive meaningful impact.

I started this site as a place to keep my own writings and document my learning journey that I'm now sharing with you.

I write about modern tools, architectures and best practices for building resilient, future-proof data systems.

Feel free to Get in Touch, I'm always open to interesting conversations and collaboration.
